U3631 | RH & Temperature Data Logger

COMET U3631 Datalogger is designed to record temperature and humidity from built-in sensors and from one external temperature probe Pt1000.
The recording is performed in a non-volatile electronic memory. The data can be transferred to a PC via USB-C.

In case of exceeded set limits alarms are indicated by LED, LCD and acoustically by built-in beeper.

Recorder includes Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.

Warranty: 3 years
